Bests & Worsts Reviews from Amazon

Weak sauce offering additional content to anyone willing to give a 5 star review. Looking at said reviews with so many 5 stars with 2 words or less written it's clearly worked for the devs but completely obfuscates any real review system. The app? It simply loops some elevator music. How does anyone know if this music actually relaxes your dog? I've seen studies on some very specific types of music working to an extent but nothing about this. I'll be honest I've had the skill playing while writing this and the loop is getting old.
